After performing a SendScreen, process the input
Since there are cases where multiple screen writes (using the SendScreen tag) may be performed in order to simulate what a real host application might do, there is a separate tag to trigger the end of sending, and the action of receiving the input.
Note that if a ReceiveInput is omitted from the onLoad event script block, an automatic ReceiveInput is generated.
ReceiveInput has no attributes or children.
Example:
<Script event="onload">
<LoadMap/>
<SendScreen clear="yes" unlock="yes"/>
<ReceiveInput/>
</Script>
